Expressions and Assignment Statements

These flashcards cover key concepts from Chapter 7 concerning expressions and assignment statements in programming languages, highlighting definitions and functions.

Expressions

Fundamental means of specifying computations in a programming language.

Arithmetic Expressions

Consist of operators, operands, parentheses, and function calls.

Operator Precedence

Defines the order in which adjacent operators of different precedence levels are evaluated.

Operator Associativity

Defines the order in which adjacent operators with the same precedence level are evaluated.

Short-Circuit Evaluation

An evaluation where the result is determined without evaluating all operands and/or operators.

Overloaded Operators

The use of an operator for more than one purpose.

Type Conversions

Processes of converting an object from one type to another, including narrowing and widening conversions.

Mixed-Mode Assignment

Assignment statements that involve operands of different types.

Functional Side Effects

Occurs when a function changes a two-way parameter or a non-local variable.

Referential Transparency

A property where any two expressions with the same value can be substituted for one another without affecting the program's outcome.

Assignment Statements

The general syntax consists of .

Compound Assignment Operators

A shorthand method for specifying a commonly needed form of assignment.

Unary Assignment Operators

Operators that combine increment and decrement operations with assignment.

Conditional Expressions

Expressions that evaluate conditions to determine which value to assign.

Explicit Type Conversions

Also known as casting, where a specific type conversion is explicitly stated in the code.

Relational Expressions

Expressions that evaluate to a Boolean representation using relational operators.

Boolean Expressions

Expressions that operate on Boolean values, resulting in Boolean outcomes.
